Section III. Concrete/Gunite Pool Installation Instructions
1. Locate position on vertical wall where light is to be installed. The top of the light lens must be a minimum of 18
inches below normal water level unless the light being used is UL listed for lesser depths. Refer to the Installation
Manual of the light for exact depth requirements.
2. Connect conduit to the niche using a recommended thread sealant.
3. Secure niche to rebar with tie wires. Orient the niche so that the pilot screw receptacle is located at the top of
the niche.
4. Connect bonding wire from rebar and bonding grid to the bonding lug at the rear of the niche.
5. Bond the niche-fixture housing to all other metallic items within five (5) feet of the pool, using a No. 8 AWG
wire. Bond connection is located at the rear of the niche. See NEC 680.26 code requirement.
6. If non-metallic conduit is used, a No. 8 AWG bonding/grounding wire must be installed through the conduit
from the Junction Box to the bonding/grounding lug inside the niche. Seal the wire/lug connection with a listed
sealant such as 3M
™
Scotchcast
™
Potting Kit 2136 or equivalent, to protect the connection from possible pool
water corrosion. See figure 2. See NEC 680.23
7. Support conduit to hold niche the proper distance in front of rebar so that the front of mounting ring is flush with
the desired finish surface.
8. If pool surface is to be plastered, you must allow proper concrete cut-back for plaster thickness. Finished
concrete surface must be cut-back behind the niche flange. Finished area surrounding niche must be flat
and flush with the brass mounting ring on the front of the niche. This ensures a snug fit between light
and wall.
